C contains an error because it needs a do-while statement, not an invalid doeswhile statement.
D contains an error because the do-while statement must end with a semicolon.
A and B are incorrect.
A is incorrect because declarations must occur outside of the dowhile statement. As such, the declaration was represented correctly in the code segment.
B is incorrect because when there is only one statement enclosed in the do-while statement, it does not need to be enclosed in braces.
